Application med November 27, 1915; serial No. 63,758. v

To all 'whom t may concern:

Be it known that I, HENRY Huss, a citizen of the United States, residingat 'Philadelphia, in thecounty of Philadelphia and State ofPennsylvania, have inventedcertain newv the end of the lead may beexposedy as the same becomes worn in use without the necessity ofcutting away the inclosing holding body.

l/Vith this end in view, my invention consists in applying a reinforcingcovering to the slender marking lead so as to produce a core, and ininclosing this core in a suitable covering to produce a holding body,the said two coverings being of such form that they may be removed insuccessive sections to eX- pose the point of the lead. By this means,and on account of the slender or attenuated character of the markinglead, no sharpening or reduction in cross section ofthe same will benecessary to4 produce a point fine enough for use, while at the sametime the slender lead willl be given such reinforcement as will enablethe main covering or holding body to be applied without danger ofbreakage of the lead.

In the accompanying drawings:

Figure l is a longitudinal section through a pencil constructed inaccordance with my invention.

Fig. 2 is a view showing how the reinforcing covering is applied to theslender lead to produce a core.

Fig. 3 is a longitudinal section through the lead and reinforcingcovering after the application of the latter.

Fig. 4 is a view showing how the core produced by the application of thereinforcing covering is inclosed in the holding body' to produce thecompleted pencil.

Referring to the drawings:

My improved pencil consists of a marking lead or crayon 1, which is ofslender or attenuated dimensions so that it will not be necessary to cutaway the material to produce a sufficiently ne point for use. In

other words, by the employment of a narrow or slender lead a markingpoint will-be presented at all times of suiiicientfinenessfor use. 2represents a reinforcing covering which is applied tothe leadfor-thepurpose of reinforcing the same and preventing lits breakage, whichwould otherwisel beapt 'to occur. The'lead and covering thusappliedforms in eect a core which is inclosed in fa holding body 3v applied totheeXterior of the core. closing body are of such -constructionand soapplied that they 1may 'be removed 'in suc'-l cessive sections from thefrontend of the pencil to expose a fresh portion of the marking lead asthev point wears away in use.

The reinforcing covering in` the present instance is in the-form ofv aflexible sheetl in diagonal relation thereto, and 'when com- Patentedaan. s, ieee@ 'I he reinforcingcovering and inpletely wound thereon itwill present at its end a conical terminal portion lc made up of theends of the over-lapping spiral coils. i

The length of the sheet is vsuch that a core will be produ-cedconsiderably less in diameter than the completed pencil, say of an inchin a pencil of an inch in diameter.

The inclosinoV body 3 consists of a sheet 3* preferably of paper andcontaining parallel weakened lines 3b, which strip is wound on the corein the same manner that the reiny forcing strip is applied to the lead,but preferably with the weakened lines at a less angle relatively to theaxis of the lead. Asa result the conical portion 3C of the body,produced by the overlapping ends of the successive coils will extend ata less slope or angle than the conical terminal portion 1 of thereinforcing covering, the latter being therefore blunter and moreabrupt, so

that it will more strongly support the marking lead at its extremeeffective point..

In the use of the pencil thus produced, when the point of themarkinglead becomes worn down, a section of the outer covering may beremoved by tearing the same along the foremostv weakened line 3*. Thiswill expose a limited `portion of the inclosed surface of thereinforcing covering, and this in turn may be removed by tearing alongthe foremost weakened `line lb so as to eX- pose a suitable surface of`the marking lead within. l

While in the accompanying drawing and foregoing description I havedisclosed my invention in the specific form which I prefer to adopt, itwill be understood that the invention is not limited to the particulardetails disclosed but that various changes, such as will suggestthemselves to those skilled in the art, may be made without departingfrom the limits of my invention. For instance the reinforcing coveringand inclosing body may be constructed of other and different forms,provided that the slender marking lead will be given proper support, andprovided that the coverings may I 'be removed in successlve sections toexpose freshportions of the lead as the same becomes worn in use.

Having thus described my invention, what I claim is: p

l. In a pencil, the combination of an attenuated marking leady orcrayon, a flexible sheet wound-thereon to produce a relatively thinpreliminary covering for the lead to reinforce vthe same againstbreakage in subsequent handling, said sheet being provided withweakening lines to permit it to be removed from the lead in sections,and a second -eXible sheet wound around the 4reinforcing lcovering andforming a stiff substantial holdingbody of relatively greater thicknessthan the reinforcing covering, said second sheet being also providedwithweakening lines to permit the same to be removed in sections. p

2. In a pencil,'the combination of a marking lead or crayon, a coveringfor the lead consisting of a paper sheet woundspirally thereon andproducing a core, an inclosing holding body for the core consisting of asheet wound spirally on the core at a different angle from that of thefirst sheet, the said sheets being adapted tol be un-Wound and removedin successive sections to expose the point of the marking lea-d; wherebythe inner covering will present-a blunter terminal portion ythan that ofthe inclosing body and will more strongly support the point of themarking lead. l

3. In a pencil, the combination of a marking lead or crayon, a coveringapplied thereto to reinforce the same and produce a core,

-and a second coveringapplied to the core to form a holding body, theends of said two coverings sloping backwardly from thel end of the lead,the reinforcing covering at a greater slope than the surroundingcovering, and said two coverings being adapted tobe removed in sectionsto expose the point of the marking lead.

In testimony whereof I have affixed my signature.

` HENRY IIESS.
